Chapter 9— Line Print Mode
EasyCoder PL-Series Printer Programmer’s Reference Manual 91
Use caution when implementing the Present-At command with preprinted
media. The media may not reposition itself exactly when it is retracted
prior to resuming printing, and the amount of this error is not repeatable
from label to label. A buffer zone of 18 dots is recommended at the
beginning and trailing edge of each receipt if you use the Present-At
command.
! U1 PRESENT-AT { units to advance after print }
! U1 PRESENT-AT
This command is discussed more fully in Chapter 8, “Advanced
Commands.”
Bar Codes and Graphics
This section explains printing bar codes and graphics in Line Print mode.
Bar Codes
The printer can make any one dimensional bar code in Line Print mode.
The Bar Code command works just like it would in a label file. For more
information, see “Bar Code Commands” in Chapter 5.
The Bar Code command is affected by the justification commands like
! U1 CENTER. For more information, see “Justification Command” in
Chapter 8.
! U1 BAR CODE { type } { width } { ratio } { height } { x } { y }
{ data }
Graphics
The printer can print PCX formatted graphics files in Line Print mode.
This printing method is not recommended in order to keep print times to
a minimum. You should load the graphic into the flash file system on the
printer to achieve maximum printing speed. For more information on
graphics, lines, boxes, and PCX commands, see Chapter 7, “Graphics.”
! U1 PCX {x coordinate} {y coordinate} !< {filename.pcx}
SETLP-Timeout Command
If the printer does not receive any characters after a set time, it begins to
print. You can set this delay with the SETLP-Timeout command.
! U1 SETLP-TIMEOUT {time in 1/8 second units}
Multiply the seconds to wait by 8 to get the correct time for the command.
Valid values for the timeout are from 0 to 255.
